The first-place Detroit Tigers reinforced the back end of their shaky bullpen Wednesday night, acquiring closer Joakim Soria from the Texas Rangers for pitching prospects Corey Knebel and Jake Thompson. The trade was completed during Texas' rain-shortened 2-1 loss to the New York Yankees. Soria said he was informed of the pending deal during the delay, and the Rangers announced the move after the game. By the time Soria spoke to reporters in the clubhouse, all his Rangers jerseys had been removed from his locker.
